It is 9 because 11 minus 2 is equal to 9.
Y=-5/2+13
Graphing it out is probably the easiest way to learn

We can't really do this without seeing 28, but I can give you an educated guess. The best way for me to proceed is to solve c.
The conjecture is that x = a + b. You should always find that to be true. C is the clincher.
Here's how you do that.
x + c = 180o That's true because all straight lines have 180o. If two angles make up the straight line that means that they are always equal to 180o So x + c = 180o
Now we move to the next step. All triangles also have 180o. That means that a + b + c = 180o
So we have two conditions that equal 180o. Equalities can be equated to one another.
a + b + c = x + c Subtract c from both sides.
a + b = x.
Study what has happened. Put in mathese, the two remote interior angles equal the exterior angle, which is what you are trying to prove.
Summary
a cannot be solved without 28
b you should say that the two remote angles (a and b) will always total x
c The proof is provided for you.

Answer:
Adult ticket = 80
Children ticket = 120
Step-by-step explanation:
Given that :
Cost of student ticket = $8
Cost of adult ticket = $10
Number of tickets sold = 200
Total amount collected = $1760
Let number of adult ticket sold = a ; children ticket = b
a + b = 200 _-_(1)
10a + 8b = 1760 ___(2)
a = 200 - b
10(200 - b) + 8b =. 1760
2000 - 10b + 8b = 1760
- 2b = 1760 - 2000
-2b = -240
b = 120
a = 200 - b
a = 200 - 120
a = 80
